MACHINE Eon OPERATING on THE so-LEs orv SHOES.

Application filed l ebruary 1a, 1922. Serial 116.?537394.

This invention relates to the manufacture of shoes'and is illustrated herein as embodied in the heel-seat fitting machine arranged to trim surplus material from the peripheral 5 portions of the heel-seats of 'soles to fit the soles for the reception of heels.

In preparing shoes for the attachment of certain types of heels having concave attachingsurfaces, of which wood heels are a typ cal example, itis necessary to trim away the peripheral portions ofthe heel-seats of't-he soles ofthe shoes in order that the heels may be attached to the shoes in such a manner that the edge of thesole is not visible between the heel and the shoe upper, At the same nailed. It is highl desirable thatthis trimming operation, W ich is commonly spoken of as heel-seat fitting, be performed with precision and that the extent of the trimming operation conform with, a considerable de- 26 gree of exactness to the -configuration of the attaching surface of theheel to be attached to the shoe so that the edge of the heel will fit closelyagai-nst the shoe uppe'r', both when the shoe is new andthrqu hout; its life and so so as to facilitate a firm an solid attachment of the heel to the shoe. v

The heel-seat fitting operation has heretofore'been ,performed for the most part by hand. s so performed, itrequires both 3 strength and skill and, at least in factories M fmaking high-grade or even fairly good medium grade shoes, it has therefore been a comparatively expensive operation.

It is accordingly an object of the present o invention to provide a'heel-seattfittin'g machine whlch -W lll be simpleand nexpensive to manufacture, rugged 1n rconstructlon and of such a nature that, with its assistance, the ordinary. run of shoe factory, help will becapable of doin a first-class heel-seat fitting job, and this wlthout requiring the exercise of; any greatstrength or unusual skill or care.

one of the moreimportant problems to the i solutionof which the invention .is directed to is the organization of the machine to operate sizes and proportions of different styles .of wood heels, regardless of the sizes of the shoes to which they are to be attached. With these problems in View, it is a further, object ofa shoe and arranged to control a suitable out;

tQlfiIIIOVELblQ peripherally of the heel-seat of a sole to trimsurplus material therefrom.- As illustrated herein, means isprovided for varying the spread of the path of movement of the cutter by, forming the guide surface on two relatively movable plates and moving these plates toward or from each other so as to vary the distance betw'een the arms of the horseshoe in accordance with the size to which the heel-seat is to be trimmed.

In accordance with another feature of the invention, the illustrated machine, is pro-- 'vided with a pair of crease plates pivotally' adjustable about a point substantially in line with the back'seam of the shoe to be operatedupon and arranged to enter or be regrip or to release the shoe, and a heel seat fitting cutter movable about the peripheral portion of the heel-seat of the sole of a shoe while said peripheral portion of the heel-seat 'issupported by the edges of said crease. plates.

Thus the shoe is held eflectively regardless moved from the rand crease of the shoe to of its size as the surplus stock is trimmed from the heel seat of its sole. 7 It is a further object of the invention to provide a heel-seat fitting machine having improved means for making the heel breast receiving out at the breast line of a sole. In

the illustrated embodiment of the invention,

this comprises aknife movable transversely of the sole and having a cutting edge ina clined relativelyto the-surface of the sole and movable clearacross the solefrom one side to the other'tomake'an inclined scarf or out commencing'toward the forward. portion of the heel-seat-and extending forwardly to the heel breast line and away fromthe tread surface of the sole, as illustrated in United States Letters Patent No. 1,527,963, granted Feb. 24,-1925,on an application filed as a division of the present application. The out made by such a. knife provides a flap of a substantial thickness where it joins the sole at about the heel breast line and tapering rearwardly to a thin edge. Such a cut of the invention relate to the controlling of the forward extent of the path of movement of the trimming cutter and the controlling of thepath of movement of the transversely moving knife which makes the heel breast receiving cut by connect-ions controlled bya heel such as is to be attached to the she e. As illustrated this heel is placed between a fixed abutmentand a movable gagemember, the latter being brought into engagement with the heel 7 part hereof:

the machine; v

and controlling by its location both the position of a stop which limits the forward move-1 ment of the trimming cutter and theposition of the transversely moving knife.

Still another feature of the invention "consists in an organization including a rotary cutter movable peripherally of the heel-seat of a sole to trim and bevel the sole for the reception of a wood heel and means for variably' controlling the operation of said cutter to adapt it to operate upon sole having heelseats ofv varying sizes and shapes.

With the above and other objects and features in view, the invention will now be described in connection with the accompanyingdrawings and pointed out in the claims. It shouldbe understood, however, that the illustrated machine is disclosed herein primarily for purposes of illustration and that various changes may be made in theor'ganization of the machine within the scope of the invention.

Referring to Figs. 21 to 24, Fig. 21 shows the bottom of the rear part of a turned shoe in which the sole 1 has been split parallel with its heel-receiving face from the rear end to its shank portion, forming a flap or apron 2 which has been folded forward. This represents the shoe'in readiness for the operation of the machine. The enlarged section of Fig. 10 illustrates the sole l'withits channel 2 and feather or extension 3, the shank or filler piece 4, the upper 5 with its lining fragmentary side ele- 6, the counter or stiffener 7, and the stitch,- ing 8 by which the inturned edge of the upper and counter are fastened to the sole.- One of the functions of the machine of 5 this application is to trim and bevel the out- .sole of a shoe around the sides and-back of the heel-seat. region, substantially as indicated'by the dotted line again Fig. 10 thus exposing the margin of the heel-seat formed bythe turned-over surface 9 of the upper and to make preparation within-this margin forthe reception ofthe concave cup or attaching surface of the lheel lQ' (Fig. 24) which is to be applied. Fig. 22 illustrates the margin 9 or overlasted portion. of theupper has been exposed so thatthe edge-of the heel may be fitted against it. Fig. 23 .illustrates the result of the next operation by which a scarf'or forwardly-(ii ping cut a tongue 13 of tapered thickness from its 'relativel thick root to its thin extremity. As seen 111 Fig. 24 this out is formed at such pointthat its base coincides with the position of the forward extremity of the attachtends entirely across the basal portion of the breast of f the heel, andin this, way a strongforward abutment is provided for the attachment of the -heel;andwhen the tongue is cemented or otherwise secured against the breast of'the heel and the apron 2 cemented over the tongue and the. remainder of the breastof the'heel and trimmed,'a

The shoe just described, is not claimed herein, since it forms thesubject-matter of Letters Patent of the United States No.

1,527,963,;granted Feb. 24, 1925', on an up,

plication filediasa division of thisiap'plication.- I

The. illustrated machine as shown particu'-' l larly Fig. 1, is'provided with a frameineluding spaced side uprights 20 connected by is a bed-plate '25 .having a corresponding recess 26. This'bed-plate has a circular re-- cess 27 in its tpp around the opening 26 as shown in-Figsfij and 11. m I a U The circular wall of this recess, which is interrupted at the front to correspond" with the entrance of the recess 24, 26, forms part of a bearing for the jaw members or crease the beveled slope ll-which is to be formed ing surface of'the heel 19; The tongue'e'x-' double lireasted covering and joint is'form'ed' plates 28, 28of -a 'shoe holder. These jaw membersare of segmental form, their outer edges bemg formed as the segments of circles of the same radius as the circular bearing recess 27. Their inner shoe-engaging portions 29 are much reduced in thickness and taper to comparatively thin edges, adapted to be introduced into the crease or crevice between '28, and their bottom surfaces slope upwardly and inwardly to provide the desired taper. The top surfaces of the rear portions of the bodies of the crease plates behind the shoulders 30 may,as shown in Fig. 11, be advantageously depressed somewhat, so as to afford a wider clearance between them and the cutt'er, hereinafter described, at the region where close approach between the cutter and the 121-has been ma'de'transv'ersely o the sole' across the front of the heel-seat,- resulting in edges, and ,a retainer-plate 32, which is se-' cured to'the plate 25 and has a circular open- -'ing 33 of somewhat smaller diameter than the recess 27, overlies these recemed edges of the jaw members and has a curved tongue 34 engaging theerecesses' for further bearing and tohold the jaw members solidly at all times horizontal and against any undesired dis placement; -The engaging portions 29 of the crease plates 28 are curved to conform substantially to the sides and back of the shoe; that is to say, these edges form between them an approximately horseshoe-shaped or U- shapedrecess having an entrance at the front,

sides which are comparatively straight or slightly curved, an'd a curved back end. By oscillating the segments in opposite directions in the rim-bearing, the engaging por tions 29 are caused laterally to approach and r'ecede in order to engage'and grip the shoe in the manner indicated, thereby holding it firmly, with the sole exposed, for operation and to release the shoe when the work has been completed. Thismovement of the jaw members'is 'efliected through forwardly diverging links 35 (Fig-'7), pivoted at their rear ends at a common point 36 to a lever 37 and passing forwardly in slots 38 in the bed- -plate25 and, pivoted at 39 at their forward ends to the under partsof the crease plate members 28 to the rear of the center off-the. circular system. Thus crease plates28 may be moved-pivotally about a point substantially in line with the back. seam of'a shoe presented to the machine, the plates entering and moving from the rand crease of, the shoe to grip or to release the shoe. Moreover, the

edges 29 of the crease plates will enter the rand crease and-grip the shoe securely, irrespective'of the size of the shoe.

' jecting arm of a bell-crank. lever 42 (Fig 11) fulcrumed at. 43 on a bracket 44, secured to the bed 23. The forwardly projecting arm of this bell-crank is pivoted at 45 to the rear endvofa lever 46, which is fulcrumed inter mediate its ends at 47 on a bracket 48 secured l to the bed, and at its forward endis provided with a handle 49 (Fig. 2) projecting at the a front of the machine.

Qanabutme'nt 51 on the rear arm of the lever -A strong spring 50 is interposed between 46 and the under side of the bed 23. This spring acts upon the-mechanism in a sense to cause the jaw members 28 to close upon the shoe. Thus, the insertion of the entering jaws -29 of the jaw members in' the rand crease of the shoe and the firm' grip which they exert q is compressed and "the clutch plate brought is produced through spring action which does not injure the shoe. The retraction ofthe jaws-is effected by manual operation upon the handle 49-. Thus the shoe is centered and positioned, as well. as held firmly in such manner as to present its sole for the action of the trimming and cutting mechanisms-hereinafter to be described.

' The. machine is provided witha work support including a post 53 carrying. at its upper end a tapered last pin 52 to receive, the last 2 carrying the shoe to be operated upon.'. Said post at its'lower portion passes through a hole in the forward part of a mounting bloclr 54 (Figs; 12, 13 and '14),which is fi'xed on a transverse rock-shaft 55 extending between the side'uprights of the frame. In the upright position the lower end ofthe post 53 rests upon onearm of a lever 56, which is fulcrumedbetween its ends on a pin 57 on the frame cross-member 21. The top flange 58 ofthis cross member isslot'ted'at 59 to 7' permit the post to pass through andfto tilt in the manner illustrated in Fig.14. A spring .60, connected at its upper end to a screw 61 on the post and at its lower end to a pin 62 projecting forwardly from the mountingblock 54, tends to pull the shoe-support post downward in the mounting 7-54. Another spring 63, connected atits opposite ends to the pin 62 on the'roclrable mounting, and to a pin '64 on the frame member 21, tends to' rock the mounting and shoe-support for- Wardly1 A stop pin 65 on thepost limits the downward movement thereof in the mounting-block.

On the under part of the mounting-block is a .canting clutch plate 66, containing a clutch loop opening 67, slightly larger than the lower part of the post 53, which passes through it. The rear end of said clutch plate is confined with freedom for slight vertical angular movement between the under side of the body of the mounting-blockand a piece 68 bolted thereto and having a ledge 69. A pin 70 secured in the rear end .ofthe clutch plate and projecting downward within a longitudinal slot71 (Fig. 14) in said ledgepre- 70 vents lateral displacement. A spring 72 interpo'sed between the clutch plate 66 and the block 54 normally holds the clutch plate tilted slightly away from the mounting-block, so

that the diagonally opposite front andrear 75 corners of its clutch loop opening 67 are in gripping relation to the pos't.- The clutch therefore permits free upward movement of the shoe-support post but willhold it rigidly at anyoperative elevation 'against descent.

The relation between the clutch plate and the underlying flange 58 *ofthe frame member- 21 is such that when the shoe-holder is tilted forward for the removal of the treatedshoe and the replacement of a fresh one, the 35 forward end of the clutch plate encounters the top of the flange 58,-so that the spring 72 flat against thebottom of the mounting-block 54, thereby releasing the grip and permitting i operating connections being such that thew holding force is superior to the force ofthe spring 63 tending to rock the support. When, however, the holding jawsare opened, the spring .63 asserts itself to'rock the sup port.- The relations are suchsthat its effect; 9

overcomes the clutch spring 72, sothatthe clutch is thereby automatically, released, per-, mitting the automatic descent ofthe post 5? under the action of the spring 60. When the shoe-support tilts forwardly, the lower end 'of the post 53 is carried rearward :away from the lever 56, as seen in Fig..14. Means areprovided for actuating the lever 56 to force theshoe-support and shoe upward against the under sides of the-blade 11.5

portions 29 of the crease plates 28 by spring action. In the particular construction illustrated in Figs. 1 and '2,'a tre'adle lever 73 is fulcrumed on the tie-rod 22 and is connected by astout spring 74, acting as a yielding transmission element, with the other arm of the lever 56, the relations being. such that depression of the treadle when the post 53 is in its vertical position over the lever 56. causes the post to be forced upward, but not by a rigid thrust which might injure the shoe or in ure or displace the jaws 28 of the shoe holder. Such upward pressure seats the last firmly upon the last pin 52 and the shoulder at the base thereof, and presses the turned-in "2 portion of the upper close against the under 76 are formed on the upper inner'portions of sides'of the-edge 29 of the crease plates 28. The clutch 66 by gripping thepost 53 against downward movement then preserves this adjustment, and insures solid support for theshoe. while being worked upon. By virtue of the disconnection between the lever 56 and the lower'endof the post'53, and the cooperation of the clutch with'the post,-the latter remains elevated'irrespective of whether the. foot-pressure is maintained upon the treadle 73 or not. A light compression spring 200, acting upon the lever 56, i s provided-for the purpose of restoring it to normal position with its arm which is beneath'the shoe-sup port post lowered.

. Secured to opposite sides of the bed 23, and

rising therefrom (Fig. 8) are blocks 7 5 formmg a further part ofthe frame of the machine. Horizontal longitudinal slide ledges said blocks, and supported slidably upon these ledges and accurately guided between the side surfaces 77 is a table? 8. The table is furtherguided and held against upward displacement by retaining strips 79 fastened to the tops of the blocks and projecting inward to occupy rabbets in the top of the table.

The t-able'7 8 is constructedof upperand lower plates-80, 81 secured together by screws 82. The opposing faces of the plates 80 and 81 form plane bearing surfaces, 'which are separated by spacer portions83 atthe sides so-as to afford a flatguid'e pocket occupying substantially the whole interior: of the table.

The plates 80 and 81 of the table are' formed with interior openings 84, 85. to permit the movement ofa-cutter-head 88, which.

in operation travels around the sides and rear of the heelseat. The lower opening 84-- maybe simply a large cavity, and may be open at the front, while the 'opening85 in the upper plate is preferably of general horse-shoe form, corresponding roughly in shape to a guide surface illustrated as a. slot 86 of a templet' 87 (Figs. 3. 4 and 5.), which lies on top of the plate 81. The opening'85 is made in this form instead of like the opening 84 in order to leave ample bearing surfaces'farthe sections of the templet to rest upon,'an'd the opening is sufficiently largerand wider than the slot in the temp'let not to :interfere with the movement of the cutter in any adjustment of the templet. A cutterhead housing 89 projects downward through the opening 84 in the lower plate of the slidable table, with its lower end in proximity to thetop of the crease plates '28 of the shoe-holder. A large plate illustrated as a disk 90' is formed on or secured to this housing, and projects widely therefrom within the flat-slide pocket in the interlor of the 7 table. The upper and lower surfaces of the disk are plane'bearing surfaces. andthe disk ary bearing surfaces of the plates 80, 81, so that the cutter-head is supported and solidly held against any deviation from the vertical upon the templet 87. A rotary cutter-shaft 98. passes vertically through the bushing 91 and through a vertical bearing in the body of the housing 89, and at its lower end bears. a'rotary beveled toothed cutter 94, the function of which is to trim and bevel the edges of i the heel-seat portion of the sole. The cutter is supported so that its bottom is spaced at a minimum clearance from the forward -portions of the holder jaw members 28 as shown in Figs. 9 and 11, and is sustained in thisposition against either upward or downward. displacement by .a collar 95 pinned to the shaft .93 and bearing on the top of the lever- '92, and by a collar 96 on the lower part of this shaft bearing against an interior shoul-' der '97 in the lower part of the housing. The lower end of the housing, below this shoulder, is formed as-an angular guard and presserfoot 98 encircling the cutter teeth and connected with the body of the housing by posts 99, the spaces between which permit the escape of the shavings.

The upperend of the shaft 93 is provided with a couplin socket 100 and screws 101 for connection wit the terminal 1020f a flexible driving shaft, receiving its power from a suitable source. The-driving shaft for the of the bushing or stem 91 of the cutter-head is accurately'guided as shown in Fig. 4.

From the foregoing it will be perceived that the rotary cutter is supported with its axis of rotation perpendicular to the plane of the sole to be operated on in such manner as to be movable universally in direc-' tions parallel with said plane.

The templet 87 is of sectional construction, enabliri it to be adjusted for shoes and heelseats 0 different sizes. In the construction illustrated the templet is divided into two J one-half each of the horse-shoe slotted guide 86, this guide consisting of two arms in the two sections and the curved connectin portion formed part in one section an part in the other. As seen in Fig. 4, for-example.

the horseshoe guide is disposed with its arms pointing to the front and the curved connecting portion at the rear. The end of the slot in the section 104 is enlarged at the outerside.

to form a lateral vestibule 107, and the opening 85in the plate 81b'eneath is correspondingly enlarged at this region. Before the cutter is brought into engagement with the shoe to be operated upon, bushing 91 is received in this vestibule, and the cutter consequently is. disposed somewhat to one side of the shoeheelregion when the table 78 is moved forward. I

The templet sections 103,104 have rearward extensions 108', 109, which are pivoted to the top of the. table on laterally spaced pivot pins 110,. 111, the construction being such that 109, these sections being formed with in-- 116, 117 on the lever. I veniently manipulated so as laterally to exwhen the sections pivot slightly in opposite directions upon these pins to vary the spread of the slot 86 the relative movement of the sections of the slot 86 at the forward ends is substantially parallel. Equal movement of the sections of the templet is effected by a lever 112' (Fig. which is pivoted at one end 113 to the top of the table and extends across the flat tops of the rearward extensions 108,

clined slots- 114,, 115 into which project pins A handle 118 on the free end ofthe lever 112 enables it to be conpand or contract the templet sections. In this Way .the templet, is adjusted for any width of heel-seat, When adjustment has been effected, the sections are locked by means of a nutj119 on the upper end of a screw stud 120, which is fixed in the top of the table and projects upward through suitable enlarged openings in the templet sections and in the lever 112. Fig. 1 shows the templet sections adjusted so asto lie close together for 'the minimum width of heel-seat, and Fig.

5' shows them slightly separated for substantially the maximum width of heel-seat.

The cutter-head is moved around in the horse-shoe slot 86 of the templet by means of a universal linkage comprising the lever or arm 92 heretoforereferred to and another arm 121.- The arm 92 carries the cutter-head intermediate between its ends, and at one end isp'rovided with ahandle 122 and at the other'end is pivoted at 123-to the arm 121. Thejtwo arms are in angular relation, and the rearend of the arm 121'swings on a relatively fixed pivot 124 on the rear. portion of v the slidable table 78. For added convenience that the slidable table 78 at the top of the machine carries the heel-seat trimming and bevellng cutter, the means for solidly supporting the same for universal two-dimensional movement over the shoe-holder, and the means for gidingor directing the cutter and for effecting its movement.

At the time when a shoe to be operated upon is put in the machine and introduced into the holder by which it'is positioned and gripped, the slidable table is in the rearward position and the stem of the cutter isin the vestibule 107 at the starting end of the slot 86 of the templet. When the shoe is in place the table is moved forward, carrying with it the cutter, which,'however, does not at this time encounter the shoe, because of being offset to the side in the vestibule. A suitable stop, such as represented for example by projections 126, 127 on the fixed frame and table respectively (Fig; '11). limits the forward movement of .the tableto a definite position in which the slot of the templet is positioned exactly over the position of the. h'eel-seat re-- gion of the shoe as determined by the shoeholder. Thev table is held forward during the trimming; and beveling' ope-ration and is then moved backward.

Mechanism is provided for, moving the table, whichmechanism is advantageously combined or united with the mechanism for elevating the shoe support post 53. In the constructionillustrated in Figs. 1 and 2 and corresponding views, a link 128' is connected at its lower end to the treadle lever73, before referred to, and extends upward through a slot in the bed 23' to a. bell-crank 129, which is pivoted at130- to the fixedframe. See Fig.v 11.. One arm of this bell crank ish pivoted at 131 to the upper end of link 128- and its other arm. is pivoted at and-slot connection. Consequently, depression of the treadle 73 not only produces yielding upward pressure on the shoe-sup- .132 to the'rear end of the table by a pin- 1 The left-hand block 75 of the upper part of the fixed frame is formed with-a'horizontal longitudinal guide slot 134, in which a slide 135 is guided for adjustment forwardly or rearwardly, this. slide having flanges 136 overlapping the 'outer and inner faces of the fixed block so as to prevent all lateral displacement.
